As a follow up question. I have another bridge in a 10 gallon shrimp tank that is starting to get overrun with algae also. How would you get the algae down? I've already turned my light down to 25% and they are on for 10.5 hours a day. I have three nerite snails in the tank but they don't seem to want to touch the algae growing on the moss. There are also 4 cherry shrimp, 4 platy fry, and a otto cat but none of them want to eat that particular algae.
